Abstract (en)

In a pulverizer of the type having, within a casing (7,10), a stator (6) and a rotor (2) to be rotated in the stator, both having large numbers of mutually confronting ridges or teeth with a gap (4) therebetween, the gap (4) is 1 mm or less, and the ridges (14) of the stator (6) are of sawtooth shape as viewed in cross section and have flanks (13a, 13b) forming troughs (13) therebetween with an acute bottom dihedral angle (a) of 45 to 60 degrees. At least one tier of a classification ring (15) is provided around the inner wall surface of the stator (6) to form flow-blocking barriers across some or all of the troughs (13) thereby to prevent particles being pulverized from being sweptthrough the troughs without being satisfactorily pulverized.
